In general, electricity is present wherever we find plasma, and since 99.999% of the visible universe is in the plasma state, magnetic field and electric currents are nearly everywhere. Almost all cosmic plasmas that have been studied in detail seem to be penetrated by magnetic fields. The presence of the magnetic fields implies that considerable electric currents must exist in the cosmic plasmas. Examples of this are found in the ionosphere and magnetosphere of the Earth. Also in more distant plasmas like the chromosphere and corona of the sun, the solar wind, and the interstellar medium we find thin structures in the form of filaments and sheets. These narrow structures are subject to the pinching action of electric currents.
